Jan 24, 2019 by Bogue formulae are presented in Table 1. Ethylene glycol and triethanol amine are used as grinding aids and strength enhancer for OPC. They are provided from Aldrich-sigma. Preparation of dry mixes During the grinding of OPC clinker in lab ball mill, the grinding aids are added with the ratios 0, 0.03, 0.04 and 0.05 wt. of the clinker with ...
Table 2 shows the Blaine area and the grindability index GI values of the dry mixes prepared from OPC in presence of different dosage of ethylene glycol EG and triethanol amine TEA after grinding for 45minutes. For OPC mixes, presence of grinding aids shows higher values of Blaine areas than the control mix.

It is recommended to use calcite with percentage less than 5, in the coming researches. Probably this percentage will present important results, in addition to using calcite additives with a mixture of two types of clay soil, in order to study its effect on this mixture. 1. INTRODUCTION
AbstractIn this study, the effects of liquid additives such as water, triethanolamine TEA and ethylene glycol EG on the dry fine grinding of calcite were investigated by using a laboratory scale vertical stirred mill. The experiments were carried out by a batch
Jan 24, 2019 Triethanol amine and ethylene glycol are used as grinding aids for Ordinary Portland Cement OPC. Standard water of consistency, Blaine area, initial and final setting times and compressive strength are tested for OPC. The phase composition and microstructure of the formed hydrates are tested using DTATG and SEM techniques.
Sep 20, 2020 1. Introduction. The history of grinding aids in dry fine grinding processes starts in the late 1930s with the application of the first commercial grinding aids in the cement industry .Since that time, the importance of grinding aids in industrial dry fine grinding processes has strongly increased so did the number of scientific papers dealing with this topic.

Abstract. Calcite and dolomite are the two most common minerals in carbonate-bearing faults and shear zones. Motivated by observations of exhumed seismogenic faults in the Italian Central Apennines, we used a rotary-shear apparatus to investigate the frictional and microstructural evolution of ca. 3 mm thick gouge layers consisting of 50 wt calcite and 50 wt dolomite.
